    摘要: A facsimile communication system and a communication apparatus reduce a loss time due to the synchronization of transmission/reception and shorten a communication time. They also shorten a communication time in a full duplex communication mode and allow proper switching of the full duplex communication at the transmission/reception replacement. DIS-CFR signals, EOP-DCN signals, NSS-TSI signals and TSI-DCS signals of a facsimile communication protocol are connected by synchronization signals so that the synchronization signals are sent even after the sending of the protocol signal. Thus, the sending of the synchronization signal for one second when the next protocol signal is sent is not necessary and a time required for the protocol signal is shortened. An ANSam signal to disable a function of an echo suppressor is sent when a call is detected and a calling station thereafter sends a protocol signal and an image signal in a manner not to cause signal interruption of 50 ms or longer, and at transmission/reception replacement at the end of the image signal from the calling station, a called station sends an ANSam signal and sends a protocol signal.

    摘要: In an image communication apparatus for communicating a color image with a distant apparatus according to the ITU-T recommendations upon line connection, an original image is read by a scanner unit, and the size of the read original image is identified. If the identified size of the original image is smaller than the page size defined by the ITU-U recommendation, image data is generated by reading the original image upon adding invalid data to the original image to make it have a main scanning length equal to the main scanning length of the minimum page size defined by the ITU-T recommendation in reading the original image through the scanner unit, and the image data is compressed by a JPEG compressing unit and transmitted. In this case, the valid image area of the compressed data is set in accordance with the size of the original image. This allows the receiving side to read only the valid image area, decode the valid image area, and reproduce the image.

    摘要: Disclosed are a monochrome facsimile apparatus capable of supporting communication of color information in sYCC color space, and a color-information communication method that uses this facsimile apparatus. If a compact flash card has been inserted into the monochrome facsimile apparatus, which is capable of communicating color file information, the facsimile apparatus notifies the transmitting side, by prescribed bits of the FIF of a DIS signal, that it has a function for receiving JPEG-coded information, lacks a function for receiving full-color information in Lab color space, and has a function for receiving full-color information in sYCC color space. If the facsimile apparatus senses, by prescribed bits of the FIF of a DCS signal, that a designation to transmit full-color information in sYCC color space has been received from the transmitting side, then the facsimile apparatus is allowed to receive color information, which is then stored on the compact flash card without being printed, by information receiving means having the function for receiving JPEG-coded information and the function for receiving full-color information in sYCC color space.
